Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554976, here are decompositions:

29 + 31554947 = 31554976
83 + 31554893 = 31554976
113 + 31554863 = 31554976
179 + 31554797 = 31554976
227 + 31554749 = 31554976
317 + 31554659 = 31554976
359 + 31554617 = 31554976
449 + 31554527 = 31554976

Showing the first eight; more decompositions exist.
